  • FIG. 1 of the drawings illustrates a conventional lock including a first handle assembly 1, a second handle assembly 2, and a latch assembly. The first handle assembly 1 includes a first rose liner 11 having two positioning posts 12 extending from a side of the first rose liner 11. The first handle assembly 1 further includes a spindle 13. The latch assembly includes a latch housing 3 having a first positioning hole 31, a second positioning hole 32, and an actuating wheel 33. In assembly, the housing 3 is mounted into a receiving hole (not labeled) in a door 9, with the first positioning hole 31, the second positioning hole 32, and a non-circular hole 331 of the actuating wheel 33 being located in a mounting hole 91 of the door 9. Next, the positioning posts 12 of the first rose liner 11 are respectively extended through the first positioning hole 31 and the second positioning hole 32 and through two positioning holes 22 in a second rose liner 21 of the second handle assembly 2. Meanwhile, the spindle 13 is extended through the non-circular hole 331 of the actuating wheel 33, thereby rapidly mounting the lock to the door 9. However, the positioning posts 12 of a certain specification can only be used with a latch housing 3 having correspondingly located first and second positioning holes 31 and 32. Namely, the first handle assembly 1 cannot be used with the latch housing 3 in a case that the distance between the first positioning hole 31 and the second positioning hole 32 is not equal to that between the positioning posts 12.
  • FIG. 2 of the drawings illustrates another conventional lock including a first handle assembly 1, a second handle assembly 2, and a latch assembly, which are substantially the same as those of the lock in FIG. 1. Further, the lock in FIG. 2 includes a reinforcing plate 8 having an axial hole 81, two pegs 82 extending from a side of the reinforcing plate 8, and a plurality of grooves 83. The respective peg 82 is at an angle with the respective adjacent groove 83. In assembly, the positioning posts 12 of the first rose liner 11 are extended through two of the grooves 83, and the pegs 82 are extended through the positioning holes 31 and 32 of the latch housing 3. Thus, the first handle assembly 1 can be attached to the latch housing 3 with the handle of either handle assembly 1, 2 being located in a position at 45 degrees with respect to a longitudinal direction of the latch housing 3, assisting disabled, aged, or children in easily opening the door 9 without changing the handle assemblies 1 and 2 and the latch assembly. Nevertheless, the distance between the pegs 82 of the reinforcing plate 8 has to be equal to that between the positioning holes 31 and 32 of the latch housing 3. Further, the reinforcing plate 8 is not reliably supported and abuts against an elastic means 14. Thus, the reinforcing plate 8 is apt to wobble and adversely affects smooth rotation of the first handle assembly 1.

  • FIG. 6 is a sectional view similar to FIG. 5, illustrating a modified embodiment of a reinforcing plate of the lock in accordance with the present invention.
  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • Preferred embodiments of the present invention are now to be described hereinafter in detail, in which the same reference numerals are used in the preferred embodiments for the same parts as those in the prior art to avoid redundant description.
  • Referring to FIGS. 3 through 5, a lock in accordance with the present invention includes a first handle assembly 1, a second handle assembly 2, an adaptor plate 4, and a latch assembly. The first handle assembly 1 includes a first rose liner 11 having two positioning posts 12 extending from a side of the first rose liner 11. The first handle assembly 1 further includes a spindle 13 and an elastic means 14. The second handle assembly 2 includes a second rose liner 21 having two positioning holes 22 through which the positioning posts 12 respectively extend.
  • The latch assembly includes a latch housing 3 having a first positioning hole 31, a second positioning hole 32, and an actuating wheel 33. Each of the first and second positioning holes 31 and 32 is a through-hole or a hole having an open side. Referring to FIG. 5, a distance “b” between the centers of the first and second positioning holes 31 and 32 is smaller (or greater, when desired) than a distance “a” between the centers of the positioning posts 12.
  • The adaptor plate 4 includes an axial hole 41, two positioning holes 42, two pegs 43 formed on a side of the adaptor plate 4, and a plurality of legs 44. The spindle 13 extends through the axial hole 41 of the adaptor plate 4. A distance “a” between the centers of the positioning holes 42 of the adaptor plate 4 is equal to that between the centers of the positioning posts 12. Each positioning hole 42 is a through-hole or a hole having an open side. The respective peg 43 is at an angle (preferably 90 degrees) with the respective positioning groove 42. A distance “b” between the centers of the pegs 43 is equal to that between the centers of the positioning holes 31 and 32 of the latch housing 3. Each leg 44 extends toward the first rose liner 11 and abuts against the first rose liner 11.
  • Referring to FIGS. 4 and 5, the adaptor plate 4 is useful when engaging the first handle assembly 1 with the latch housing 3 in a case that a distance between the centers of the positioning holes 31 and 32 that is not equal to the distance between the centers of the positioning rods 12. The positioning posts 12 of the first rose liner 11 are respectively extended through the positioning holes 42 of the adaptor plate 4, and the spindle 13 is extended through the axial hole 41 of the adaptor plate 4, with the legs 44 pressing abutting against the first rose liner 11. Thus, the adaptor plate 4 does not contact the elastic means 14 and thus would not interfere with operation of the elastic means 14. Next, the pegs 43 of the adaptor plate 4 are respectively extended through the first positioning hole 31 and the second positioning hole 32 of the latch housing 3. Thus, the handle assembly having a certain specification (i.e., a fixed distance between the positioning posts 12 of the inside rose liner 11) can be used with latch housings 3 with various distances between the positioning holes 31 and 32 through the use of the adaptor plate 4. A manufacturer may produce adaptor plates 4 of various specifications for latch housings having various specifications (i.e., various distances between the positioning holes 31 and 32). The overall cost for the molds for manufacturing the adaptor plates 4 is much lower than the cost for manufacturing handle assemblies of various specifications and latch housings of various specifications.
  • FIG. 6 of the drawings illustrates a modified embodiment of the adaptor plate 4. In this embodiment, in a case that the distance “a” between the centers of the positioning posts 12 of the first handle assembly 1 is smaller that the distance “c” between the centers of the first and second positioning holes 31 and 32 of the latch housing 3. In this case, an adaptor plate 4 including two pegs 43 whose centers having a distance “c” therebetween can be used. Thus, the first handle assembly 1 can be rapidly coupled to the latch housing 3 through the use of the adaptor plate 4. The positioning hole 42 of the adaptor plate 4 can be U-shaped. Similar to the above embodiment, the assembling tolerance and application range for assembling the first handle assembly 1 and the latch assembly are increased, and the cost for assembling and manufacturing is reduced.
  • Still referring to FIGS. 5 and 6, the legs 44 of the adaptor plate 4 can be fixed to the first rose liner 11 by snapping members, screws, welding, or heat pressing, further improving the assembling reliability and the assembling stability.
  • While the principles of this invention have been disclosed in connection with specific embodiments, it should be understood by those skilled in the art that these descriptions are not intended to limit the scope of the invention, and that any modification and variation without departing the spirit of the invention is intended to be covered by the scope of this invention defined only by the appended claims.
